right I'm going to fit a bypass valve anyway but each zone will have one radiator which has normal valves one in the downstairs hallway as the downstairs thermostat is in the hallway and the upstairs zone will have a normal valve on the master bedroom radiator as that is where the upstairs...

Bumping this thread again as I'm still altering the pipework and have a couple more questions if you don't mind me asking. I am installing the upstairs thermostat in the master bedroom, but can I still have a TRV on this radiator and do i need to have a smaller radiator in the bedroom or can I...

I am not a heating engineer so don’t quote me on this but I use to own a house with one of these fitted with the bubble. I was instructed by my regular engineer that these need to serviced once a year and part of this service replenishes the air bubble in the tank

As said above the system wouldn’t work correctly you could wire it together and lash it up to work but the 2 nests would counter act eachother. The extension underfloor Nest would bring the boiler on and heat all the other radiators in the house. It would be better to not have the control of a...

You can have more than one nest thermostat to control the heating. To zone the extension property then a new zone valve needs installing from the flowfrom theboiler. If you do it the way you have said then you won’t get heat on the new zone untill the main exsiating valve opens so it’s a...

Thank you Stem for your explanation of the correct thermostat location. I will fit the thermostat in the master bedroom instead. With regards to my other questions Am I ok just to lift the flows of the upstairs radiators ? Or should the returns be lifted and run back to the same location as...

So it would be better to have another non Trv valve on the new upstairs zone. The new thermostat is to be fitted on the landing to control the new zone so will leave the landing radiator without a trv So to make the new upstairs zone all I have to do is lift the flows of all the upstairs...

Thanks for the reply At the moment there is a 22mm flow from the boiler to 2 zone valves one for the radiators and one for the presurised hot water tank the radiator return 22mm and 22mm from the hot water coil then tee into the 22mm return back to the boiler. I am looking at lifting the 5...

I am having the heating system upgraded in my house and currently have all the floorboards up. I have found all the manifold points for all the radiators in the house. At the moment they are all on one zone. I am wanting to split these into 2 zones upstairs and downstairs. My question is do I...

Thanks to crank39 for all the very useful info I think if i can confirm the window seals then I might have a go at some point and take the full frame out and try and swap it around. I have included some pictures of the window glazing beads inside and out and the door beads inside and out. I...

Its the dwarf walls and the window cills and skirting board. So the dwarf walls need to be cut back then replastered and the window cills and skirting to be trimmed back. to me it would be better for the doors to open outwards into the garden and personally looking at the doors the face that is...

Ok thanks for the advice. I need to see whats going to be the best option. If i manage to prize the doorframe apart then the hinges will be fine on the outside yes? or do i need to swap these for external hinges ? Also as the water vents at the bottom will then be on the inside is it ok to seal...

Right so if the doors have been fitted correctly whats the best way to rectify the fact that the doors do not open properly? Should I cut back the dwarf walls window cills and skirting to mean that the doors can open inwards fully. I would also have to swap the handles round so that the fixing...

Thanks to everyone who has replied. I think they have definitely been fitted the wrong way round so I am going to swap the frame around. I have enclosed a few more pictures and i would appreciate if those in the know could confirm what they think. My only concern now is if i swap them around...

Hi I hope that someone can confirm one way or other which way round my patio doors should be. I have just brought a new to me house and the patio doors open inwards with the hinges on the inside. I think the doors have been fitted the wrong way round by the builder. I would be grateful if...

Glad you got the stat working

You need to remove the wired thermostat wiring from the wiring centre this then gets connected into the nest home link to give the nest stat 12v from the home link you then remove the 230v thermostat and connect the nest stat to the cabling do not connect the stat first but install the...

The nest link basically is a 2 zone controller 1 for heating and one for water and you configure it how you need it. To control the underfloor heating u would need a nest thermostat per heating zone/ actuator or wire all the actuators together to the one nest thermostat Which is a bit pointless

If you struggle to get a fixing you might have to stick the box in I use a mix of bonding plaster and cement. the cement makes the bonding go of super quick you can then make the mix stiff and stick the box in. Leave it half an hour and it's solid Rough mix of 75% bonding plaster...

I rember when I first started it's actually not that long ago Right you have a fault on the ring circuit if you have just recently qualified this should be fresh I'm your head. Bearing in mind that you have continuity on r1 ,rn and r2 this confirms that the ring is indeed a ring if there...
